Description

Technical Field

[0001] This utility model relates to the technical field of resin sand production, and in particular to a curing device for resin sand production with automatic feeding. Background Technology

[0002] Resin sand refers to molding sand or core sand that uses synthetic resin as a binder for sand particles. After the mold or core is made from resin sand, the resin undergoes an irreversible cross-linking reaction and solidifies through the action of a curing agent, thereby giving the mold or core the necessary strength.

[0003] In the prior art, patent document CN222175841U discloses an automatic feeding curing device for resin sand production, including a support plate with legs fixedly connected to its four corners, a base plate below the legs, a solidification component on top of the base plate, a mixing tank fixedly connected inside the support plate, a cover plate on top of the mixing tank, and a valve assembly fixedly connected above the cover plate. In this automatic feeding curing device for resin sand production, the stirred raw material is injected into the solidification component. After the solidification component is moved to a dry area, a heating plate is activated to solidify the raw material. Once completely solidified, pulling the handle moves a baffle upwards, which in turn moves a sliding rod upwards, facilitating the removal of the resin block. After the raw material is discharged from the mixing tank, the stirring process can be restarted, thereby improving work efficiency and accelerating the production of resin blocks.

[0004] During use, it was found that the above-mentioned device transports the solidification component to the base plate, receives the material, and then moves the solidification component away. The narrow space between the base plate and the support legs makes it inconvenient for workers to move the solidification component. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic feeding curing device for resin sand production.

[0006] This utility model discloses an automatic feeding curing device for resin sand production, comprising a support frame and a mixing drum. The mixing drum is fixedly installed at the top of the support frame, and a discharge pipe is provided at the bottom of the mixing drum. A solenoid valve is installed on the discharge pipe. The device also includes a mixing component, a receiving component, and a solidification component. The mixing component is installed on the mixing drum, and the receiving component is located between the support frame and the mixing drum. The receiving component is used to convey the solidification component. In use, various materials enter the mixing drum, the mixing component is activated, and after mixing the various raw materials, a set of solidification components is placed on the receiving component. The receiving component moves the set of solidification components to directly below the discharge pipe, and the solenoid valve is opened, allowing the mixed raw materials inside the mixing drum to enter the solidification components through the discharge pipe. After receiving the materials, the receiving component conveys the set of solidification components backward and also conveys another set of solidification components through the receiving component, providing workers with ample space to move the solidification components and improving the convenience of handling.

[0007] Preferably, the mixing assembly includes a primary motor, a reducer, a coupling, a rotating shaft, connecting rods, helical blades, and a support frame. A support frame is mounted on the support frame, and a reducer is installed at the top of the support frame. A primary motor is mounted on the reducer, and the output end of the primary motor is connected to the input end of the reducer. The output end of the reducer is connected to the right end of the rotating shaft via a coupling. The rotating shaft passes through and is rotatably connected to the mixing drum. The helical blades are mounted on the rotating shaft inside the mixing drum via multiple sets of connecting rods. When multiple raw materials enter the mixing drum, the primary motor is started, causing the reducer to drive the rotating shaft to rotate with the coupling. The rotating shaft drives the helical blades to rotate inside the mixing drum via connecting rods. The helical blades mix and stir the multiple raw materials inside the mixing drum, improving mixing efficiency. When the solidification component receives material, the primary motor continues to run, causing the multiple sets of helical blades to continuously agitate the raw materials.

[0008] Preferably, the receiving assembly includes a conveyor frame, conveyor rollers, auxiliary rollers, a conveyor belt, and a drive motor. The conveyor frame is mounted on the top of the support frame. Two sets of conveyor rollers and multiple sets of auxiliary rollers are rotatably mounted on the conveyor frame, with the multiple sets of auxiliary rollers positioned between the two sets of conveyor rollers. A conveyor belt is fitted around the outside of the two sets of conveyor rollers. The drive motor is mounted on the conveyor frame, and the output end of the drive motor is connected to one end of one set of conveyor rollers. During receiving, the worker places one set of solidification components on the conveyor belt and starts the drive motor, causing the two sets of conveyor rollers to rotate the conveyor belt in cooperation with the multiple sets of auxiliary rollers. The conveyor belt moves the solidification components directly below the discharge pipe for receiving. After receiving, the drive motor is started again, causing the conveyor belt to continue moving the solidification components that have been received, facilitating the worker's handling of the solidification components containing raw materials in a spacious area.

[0009] Preferably, the solidification assembly includes a receiving box, a heating plate, and a handle. The heating plate is provided on the inner side wall of the receiving box, and the handle is installed on the top of the receiving box. The operator moves the receiving box onto the drive motor using the handle. The receiving box receives the raw materials. Afterward, the operator moves the receiving box containing the raw materials away using the handle. Then, the heating plate is energized to heat and solidify the raw materials.

[0010] Preferably, it also includes positioning markers, with multiple sets of positioning markers evenly spaced on the outer wall of the conveyor belt; with the help of the positioning markers, the staff can accurately place the receiving box.

[0011] Preferably, it also includes a protective cover, on which the bracket is provided, and the coupling is inside the protective cover; the protective cover is outside the coupling to prevent the coupling from tangling with the workers' clothes and causing danger when it rotates.

[0012] Preferably, it also includes a feeding hopper, and the input end of the mixing drum is provided with a feeding hopper; the raw materials enter the mixing drum quickly with the help of the feeding hopper, improving the ease of operation.

[0013] Preferably, it also includes a handle cover, on which the handle is fitted; the staff can grip the handle with the handle cover to reduce the occurrence of the handle slipping.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, various materials enter the mixing drum, the mixing component is started, and after the mixing component mixes and stirs the various raw materials, a set of solidification components is placed on the receiving component. The receiving component moves the set of solidification components to directly below the discharge pipe, and the solenoid valve is opened, so that the mixed raw materials inside the mixing drum enter the solidification components through the discharge pipe. After receiving the materials, the receiving component conveys the set of solidification components backward, and also conveys another set of solidification components through the receiving component, so that the workers can move the solidification components in a wide space, improving the convenience of handling.
